Occurrence and distribution of larval and juvenile fish was investigated in nearshore waters of the southeastern Caspian Sea including the Gorgan Bay. Samples were collected during seven surveys using a fine mesh beach-seine in five sampling sites from July 2014 to June 2015. A total of 15500 individuals mostly juvenile were captured, representing 18 species from 8 families. Most juveniles belo...

during the recent years, there has been an increasing interest toward dietary administration of synbiotic to improve growth, immunity and physiology of fish. the aim of this study was to evaluate the effects of feeding on synbiotic (pediococcus acidilactici and fructooligosaccharide) enriched adult artemia franciscana on growth indices, intestinal microbiota and stress resistance of angel fish ...

A 50-day feeding trial was conducted to evaluate the effects of yeast nucleotide in diets on growth performance, serum immune indices and muscle composition of Ancherythroculter nigrocauda (mean initial body weight, 23.30±0.59 g). Seven isonitrogenous (approximately 42.76% crude protein) and isoenergetic (17.43 KJ g−1 gross energy) experimental diets with varying levels of yeast nucleotide (0[c...

Background: Aflatoxin contamination is a common natural phenomenon that is difficult to avoid or control and it can occur during pre and post-harvest periods under high humidity and temperature conditions, and are potentially dangerous to fish. In the present study, a feeding trial evaluated the effects of diets contaminated with aflatoxin on certain immunological parameters of common carp. Me...

There is a long-standing debate whether mangrove and seagrass habitats in the IndoPacific region function as nurseries for coral reef fishes. We studied the use of all major shallow-water habitat types by juvenile coral reef fish using visual census surveys at 4 islands along the Tanzanian coast (East Africa) and at the island of Grande Comoros (Comoros archipelago). We investigated the value o...

Objective- The present study describes the anesthetic effects of essential oil of Lavender (Lavandula officinalis) in Convict cichlid fish (Cichlasoma nigrofasciata) in comparison with clove powder (Syzygium aromaticum).Study Design- experimental studyAnimals- 25 Juvenile Convict cichlid fish with unknown sex and an average weight o...

The present study evaluated the potentiality of cage culture stinging catfish (Heteropneustes fossilis) under different feeding regimes. Fish experiments were consists three treatments (T1, T2 and T3), each with replicates, lasted for 90 days. stocking density was 300 fry (~1.5 g) per cage. given commercial floating feed (28% crude protein) twice daily (in morning evening) at 5% (T1), 7% (T2) 9...

  Apparent digestibility coefficients (ADC) were calculated by using chromic oxide in the diet as an indigestible marker to evaluate the Iranian Cottonseed meal (CSMP) . Then, the nutritional value of cottonseed meal ( ‍ CSM) as soybean meal (SBM) substitute in quality low cost rainbow trout (Oncorhynchus mykiss) ration was investigated. In this study, six formulated feeds consisting different ...

The present study aimed to analyze the concentration of aromatic hydrocarbon transfer cyclic through consumption of Binni fish (Mesopotamichthys sharpeyi) at Huralazim wetland and estimates the risk of consumption at 7 stations of Huralazim wetland in spring 2018 (one season). A statistic populations included sediment (n=21), water (n=21) and fish (n=21). The concentration of aromatic hydrocarb...
